In physics, the Coriolis effect is a deflection of moving objects when they are viewed in a rotating reference frame. In a reference frame with clockwise rotation, the deflection is to the left of the motion of the object; in one with counter-clockwise rotation, the deflection is to the right.
The following simulation help you visualize the Coriolis effect!


Click the following image to show the simulation.

I have recreated a JavaScript version of this simulation

enjoy!

Dear Prof Hwang,

I think I fixed a bug

//x3=x-y*Math.sin(c); //Rotating with Disk Viewpoint apparent trajectory
//y3=y-y*(1-Math.cos(c));
x3=x+y*Math.sin(c); //Rotating with Disk Viewpoint apparent trajectory MUST change to + instead of -
y3=y-y*(1-Math.cos(c));
//if(y<-R)_initialize();
if(y<-R)_pause(); // added pause by lookang
//vx3=vx-y*w*Math.cos(c)-vy*Math.sin(c);
//vy3=vy-y*w*Math.sin(c)-vy*(1-Math.cos(c));
vx3=vx+y*w*Math.cos(c)+vy*Math.sin(c); // differentiate
vy3=vy-y*w*Math.sin(c)-vy*(1-Math.cos(c));

Then the rotation is correct
